Thanks everyone for your responses.
I did go to the asian areas in the uk (places in london, birmingham, Bradford, Leicester), but the problem is it takes about four months turnaround so I won’t get the dress in time. At least their honest!
My inlaws have kindly said that if I choose something I like then they will get their taylor in Pakistan to get it sorted. That’s where my walima outfit is being made, they have had other bridal dresses made for friends of the family and they are reliable. That seems like the best option to me and I know that it will be good quality and I should get it on time.
I never thought something like a wedding dress would cause so much anxiety!
